Womanizer by Britney Spears is featured in Britney 2.0, the second episode of Season Four. It is sung by Tina and Unique with Marley and the girls of McKinley High as back-up.

While forming a new friendship with Marley, Unique wants to know who she has an eye on. Marley explains that she thinks Jake is kind of cute, but Unique shakes her head and points out that he is clearly a womanizer. The song then begins.

Marley watches Tina and Unique sing before she joins in. The scene intercuts from the McKinley hallways, classrooms and the gymnasium. As the three progress around the school, more girls from the school join in the song and performance.

Orange liquid flows from the volcano that Jake and the Cheerio are working on, but when Marley joins the rest of the girls, the volcano is seen with nothing flowing from it.
